Etlina's Principle

Etlina's Principle is a 3DCG visual novel set in a dystopian future where humanity has been transformed by a parasitic symbiote called Nox Limax. Three years after discovery, the organism mutated and began converting humans and the environment into alien-like creatures, turning cities into dangerous wastelands. You play as a member of HOWL Squad, an elite military unit tasked with dangerous operations in this transformed world. The game combines story-driven gameplay with squad management and character relationships as you navigate conflicting factions—corrupted humans, transformed hybrids, and those resisting infection—and ultimately decide who poses the real threat to humanity's survival.
